Application filed October 31, 1912. Serial No. 728,831.

e To all 40h am it may concern for this purpose.

' tor while at the borough of Brooklyn,

chines of accompanying drawings, which form a cleaning fluid will receive Be it. .known that I, Louis STRIMBAN, a citizen of the United States, residing at in the city of New York,- county of-Kin'gs, and State of New York, have invented certain new and useful Improvements in Dish-Washing Maliich the following-is a specification, reference being had therein tothe part thereof.

My invention relates to dish washing machines, and more particularly to a type thereof wherein a reticulated container for soiled dishes is adapted to be immersed in the cleaning'fiuid.

The main object of the invention is to provide a machine of this character where in the dishes as they are immersed in the both vertical and lateral motion in a manner to bring said fluid into a more intimate relation with all of the dishes in the container, thus tending to more thoroughly and more rapidly cleanse the dishes,

A further object is to provide a machine of this character wherein the support for the container may be. removed from above the cleansing bath in a manner to facilitate the mounting or removal of the container While at the same time avoiding the necessity for the operator to lean over the bath A still further object is to provide a machine of this character wherein the support for the container will automatically descend into the cleaning bath and through its descent will have imparted thereto a rotative movement about a vertical axis in a manner to cause the fluid to pass both vertically and horizontally between the dishes. And a still further object is to provide a ma chine of this character wherein the vertical and lateral movement of the container may be repeated by means of a mechanism which will be conveniently accessible to the operathe same time permitting a rapid actuation of the support for the container. so

The invention consists primarily in a dish washing machine embodying therein a tank adapted to receive a cleaning fluid, a support for a container for soiled dishes, a bridge having a vertical bearing therein for said support cotiperating means carried by said bridge and said support whereby said support is adapted to. receive simultaneous vertical and lateral movement, and manually opera tive means for raising and lowering said support in said bearing; and in such other novel features of construction and combination of parts as are hereinafter set forth and described, and more particularly pointed out in the claims hereto appended.

Referring to the drawings: Figure 1 1s a side elevation of' a machine embodying my invention; Fig. 2 is a front view thereof, and Fig. 3 is a detail of the mechanism whereby the vertical reciprocation is imarted to said su port.

Like letters re or to out the several views.

In the embodiment of my invention shown in the drawings, a indicates a tank adapted to receive cleaning fluid. Discharging into this tank are the hot and cold water pipes b and c and leading therefrom is a waste pipe d and an overflow pipe 6. Projecting upwardly from the tank a are two oppositely disposed standards and g suitably placed, and mounted upon the tops of these standards is a bridge 71. having therein a bearing h for the reciprocatory member of a support for a container for the dishes, and an interiorly threaded sleeve h in vertical alinement therewith- Slidably mounted in the bearing h is a sleeve 5 and rotatably mounted in said sleeve and held against axial movement therein by the collar j is a worm shaft is meshing'with the threads in the sleeve 7L2- Upon the lower end of this worm'shaft is mounted a collar Z carry-' ing hooks m adapted to receive the handle of a container for the dishes to be cleaned. The sleeve a is limited toa direct vertical movement and upon one face thereof is formed a rack 11, b means of which this like parts throughsleeve and the shaft may be simultane- Carried by the 'while the other end thereof is provided with a suitable hook adapted to slide over and engage the other standard By this means the entire bridge may be swung laterally of the machine so as to remove it from immediately above the tank in order to facilitate the application or removal of the dish ontainer thereto or therefrom. The. ac-

tuating mechanism being carried in its entirety by this bridge, it is possible to move this bridge in the mamier described with, out possibility of disarrangement of parts. Adjacent to one end of the machine is a receiving tabler. i H

To receive the dishes to be cleansed, I provide a container comprising a reticulated basket body 8 having a bail handle 8 provided with a central looped portion 8 adapted to pass over and snugly fit upon the hooks m. Secured to the looped portion 8 is a wooden hahdle s which is usedbecause of the low heatconductivity of this material. Mounted upon and passing through the bearing h is a set screw it having a handle t, the function of which set screw is'to lock the sleeve 71 in position relative to the bridge k.

The operation of the herein described device is substantially as follows': In using the device, the sleeve 2' and worm shaft is are raised by means of the rack and pinion n p so as to bring the hooks m adjacent to the bridge A. The said bridge is then swung upon the standard f until said hooks -are above the table 1'. The container 8 is'then mounted upon the hooks m by means of the loopedportion s of the handle a, and the bridge swung to its former position, the hook of said bridge fitting over the other standard 9. The set screw t which while the container is being mounted upon the hooks m is set to hold the sleeved and worm shaft is in the raised position, is then released, the weight of the said container and its contents causing them to descend into the tank a. The sleeve i during this descent moves merely vertically, but the shaft 70 through the engagement thereof with the interiorly screw threaded sleeve k rotates the said shaft and with it the container, thus causing the said container to have both a vertical and a rotary movement upon entering the cleaning bath. The handle p may then be used to repeatedly raise and lower the sleeve 27, the shaft is with'the vertical movement of this sleeve having imparted thereto a simultaneous rotary movement so as to cause the cleaning bath to come into contact with all portions of the dishes 'con-' the bridge it may again be swung laterally so as to bring the. container above the drip table 1* where it may be conveniently removed from the hooks m and the dishes be permitted to drain before removing to-the drying table. The water pipes b, c,- overflow pipe 6 and drain pipe d are-used to control the quantity and temperature of the water in the bath, and the wooden handles upon the container is for the purpose of permitting the convenient handling of this container when removing it from the. bath, at which time the metallic portions of thecontainer would be extremely hot.

It will be observed that by the construction herein shown and described, not only may the container be quickly mounted upon the hooks m or sec ured in position in the machine, but that when once so secured the dishes may be violently agitated within the bath with the expenditure of but small energy on the part of the operator, and that by reason of the automatic simultaneous Vertical and rotary movement of 'the support for the container, the dishes may be more thoroughly and more rapidly cleansed than by a mere submersion thereof in the bath.

It is not my intention to limit the inven-v tion to the precise details of construction shown in the accompanying drawings, it being apparent that such may be varied Without departing from the spirit and scope of the invention.

Having described my invention, what I claim as new and desire to have protected by Letters Patent, is
